As for US residential powerlines... this should be a major design concern for Bitmain or any other miner mfgr because PSU's do NOT like low lines... In Detroit area home power is 110v - not 120 - and during summer will often drop to 100-105v. The '220v' incoming reflects the same drops. This year it got so bad (hit 95v for 2 weeks) I had to wire in a boost transformer to make up the difference...

I'm not sure anything can be done for that. The vast majority of the market doesn't have that problem, and one which will affect all electronics.

'All electronics' - and more. Gas clothes dryers and stoves did not want to work either because the igniters would not come up to temp...

In this instance the problem only really affects PSU's being pushed to near max output. What to be done? Easy answer, appropriately de-rate the PSUs like HP did with their CS server PSU's so it can run on a low line and still produce required power. Then it is just a matter of balancing cost/benefit. Frankly, given how vocal folks can be here when there is an issue I'd err on making sure they can go down to at least 100v to cover wiring in old homes & apartments.

So if I'm reading this right, S4 started a bit rough but may turn out to be a decent miner:

- faulty PSUs are being replaced, hopefully new batches won't have the issue
- thanks to ck it now works on most pools including p2pool
- overclocks to 2.2+ TH without too much effort

The only thing left to take care of is the price.

Does Ck's custom S4 cgminer build located here: http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer still need the difficulty manually set on the pools?

No it doesn't, that was one of the major fixes that went into it.

Ironic, then, that your build (141018) is dated two days after the timestamp on their latest, long-awaited firmware release: initramfs.bin.SD-20141016.tar.gz which, although timestamped October 16, was not actually released until the 27th...

I wonder if they *knew* the firmware that took them two weeks to package, and two more to test and release, was already obsolete, but chose to release it anyway, or if they're just that clueless... Wait, no. I don't actually wonder that at all -- I'm pretty sure I know!

Btw, does anyone know if the new update allows you to mine on eligius now?

I'm testing eligius with 1 S4 right now, it assigned 2048 diff shares pretty quickly, looking good so far. I;ll post back with stats soon. Any other pools anyone wants tested while I'm at it?

Works perfectly with ck's custom cgminer. Haven't tried with the stock cgminer that comes with the new FW update.

Im referring to bitmains firmware update, cause im a noob and dont know how to use ck's version, on that note, im testing it on eligius myself, so far seems to be working really well

just got my tracking number too.. but here's the question, do they expect us to pay for the import duty? and same with sending their psu back to them as suggested in the last email? cause thats gonna hurt my wallet if i have to pay for that again..

Duty? Not in the US at least. Is part of the shipping cost.
As for returns/replacements. No duty as long as parts are marked as warranty replacements. Even if Bitmain wants to old one back as long as marked as a Return no duty applies (plus if any did would be their problem, not yours)

the last time i had an issue with the s2 they took the old hashboard back, they were meant to pay the duty, they didnt pay it, and ups were up my ass for the money, so in the end i had to pay for that too

... We ship things to/from Asia all the time and never came across that before. I'd try and go after Bitmain for the monies. If anything to make it more palatable to them (though it IS their responsibility) email support an offer to buy a set of s3's if they deduct the current btc value of the duty?

The sender has the responsibility as marking it "warranty replacement part" .. I think if you do that the duty should be waved . mark the value of the defective part "0.00"

No?

Yeah I tried to do that, but UPS were being pricks and wouldn't take the part with it valued at 0.00, i had to arrange a delivery a good 3 times, and eventually i had to put a number on it higher than 0

Unknown, CK might have to make a few tweaks.

Quote from: NotFuzzyWarm on October 29, 2014, 09:35:10 AM

Anyone know if the changes CK made will be put into an official Bitmain update so it is not lost on hard-boot?

In time, engineers have only just seen the code and will have to investigate the changes.

So I shouldn't bother setting expiry and scan-time?

Well, they're sort of left over from the CPU/GPU mining days - asics shouldn't need them, I don't think they'll do any harm though, but I'm not sure tbh as I've never used those commands with asics.

Thanks for that, I did wonder if you'd used the zero setting for queue.....expiry & scan time are pretty obsolete now though.

No problem! I'm pretty new to p2pool, and I stumbled across those settings somewhere. So I shouldn't bother setting expiry and scan-time?

I've been mining with p2pool lately and it's working perfectly.

Would you mind sharing the miner settings you're using with p2pool? Also, what is your reject/doa rate with the S4 & p2pool?

Thanks.

That's with 2 S4s running. Latest firmware installed (10-16) with ck's custom cgminer, each running at 225MHz. I edited cgminer.sh, changing queue from 8192 to 0, and added expiry 1 and scan-time 1. Share difficulty manually set to 2048.

Would ckolivas latest cgminer for the S4 be better then "initramfs.bin.SD-20141016.tar.gz"? Since ckolivas's cgminer is dated 10-18-2014, and bitmains firmware is dated 10-16-2014?

I'd like to know this too. Does the new firmware incorporate what CK has submitted to them and work as well as his current release? I've got one using original firmware with CK update and have 2 more suppose to show up today or tomorrow.

It's a shame there were so many S4's out with problems.

Mine came in, I manually set difficulty, increased the frequency and consistently hash at 2.3TH no problem and no complaints.

ditto. 1st tried Eclipse - as 'stock' one s4 would not go over 25-30ghs and the other one - that arrived only 1 day later - does better holding @ 1.68THs on EMC. Applied CK's tweak and both now rock-solid at 1.98-2.28THs.

Anyone know if the changes CK made will be put into an official Bitmain update so it is not lost on hard-boot?

OR - since it seems the S4 is running off of a RAMdisk created on boot and loaded with the miners running files, anyone know where the master copy of the CGminer file is located and if it can be replaced with CK's tweaked one?

Same here with my B2. My B1's PSU died, but it was replaced quickly. All in all I'm a fan of the S4s. CK's updated cgminer helped a lot too.

You are a fan of a miner that won't let you choose what pool you want to use? I use eligius exclusively and I didn't read ANYWHERE on BITMAINTECH.com that the S4 would be exclusive to pools that allowed you to set minimum difficulty. So to me, even IF I could get my S4 working, it would still be worthless, because I can't use the pool that I choose. Why am I the only one who finds this outrageous?

I can mine pretty much anywhere with them since I updated to the latest firmware + installed Ck's custom S4 cgminer build. I haven't tested eligius for a while, and while it didn't work earlier I'm confident it would now. I could test it if you're curious?

Not sure but in any case it can't hurt. 2048 is right for a 2TH miner.
